WP ERP WordPress Plugin | versions before 1.13.4

How the Exploit Works

The exploit takes advantage of a flaw in the WP ERP plugin’s parameter handling. An attacker, who is an employee, can manipulate parameters to gain unauthorized access to sensitive data of terminated employees. This could lead to potential system compromise or data leakage if the exposed data includes login credentials or other sensitive information.

Conceptual Example Code

A theoretical exploit might involve sending a malicious HTTP request, such as:

GET /erp-api/employees/terminated/id HTTP/1.1
Host: target.example.com
Authorization: Bearer {employee_token}
{ "id": "terminated_employee_id" }

In this example, `terminated_employee_id` would be the ID of a terminated employee, and `employee_token` would be the token of an active employee. This could potentially return sensitive data of the terminated employee.

Mitigation Guidance

To mitigate this vulnerability, users are advised to upgrade the WP ERP WordPress plugin to version 1.13.4 or later. If this is not immediately possible, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure to detect and block attempts to exploit this vulnerability.
